When close to half the companies in China have price-to-earnings ratios (or "P/E's") above 30x, you may consider Jiangsu Linyang Energy Co., Ltd. (SHSE:601222) as a highly attractive investment with its 12.6x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

Recent times have been advantageous for Jiangsu Linyang Energy as its earnings have been rising faster than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

Jiangsu Linyang Energy's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Retrospectively, the last year delivered an exceptional 38% gain to the company's bottom line. However, this wasn't enough as the latest three year period has seen a very unpleasant 11% drop in EPS in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Looking ahead now, EPS is anticipated to climb by 23% during the coming year according to the three analysts following the company. Meanwhile, the rest of the market is forecast to expand by 35%, which is noticeably more attractive.

In light of this, it's understandable that Jiangsu Linyang Energy's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Jiangsu Linyang Energy's analyst forecasts revealed that its inferior earnings outlook is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Jiangsu Linyang Energy, and understanding should be part of your investment process.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with a strong growth track record, trading on a low P/E.
